The CMX-200 has a measurement frequency range of 1.8 to 200 MHz and can measure from the HF band to the VHF band.

The meter can simultaneously measure traveling wave, reflected wave, and SWR value by adopting the cross method.

The sensor is designed as a pass-through type, which minimizes power loss due to connection and allows measurement without disturbing the power supply conditions from the radio to the antenna.

The meter scale plate is equipped with an illumination lamp, which lights up at night for easy viewing (when an external power supply is connected).
